Purpose
Validates distribution function string.
Synopsis
- string = ck_function(string)
Description
Translates various function string names into internal keyword. Abbreviations can be used with distribution function. For instance, the following example will produce the density distribution at x:
>> n = normdf('d',x);
Inputs
- 'cumulative' 'c' 'cdf'
- 'density' 'd' 'pdf'
- 'quantile' 'q' 'inv' 'inverse'
- 'random' 'r'
Outputs
'cumulative'
'density'
'quantile'
'random'
